lo @ZL w/wwt it may concern:

Be it known that l, THOMAS K. OBER, a

vcitizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certainImprovements in Braiding-Machines, of

which the following is a specification.

y This invention relates to mechanism for weaving circular or tubularbraid and its .primary object is to provide an improved machine havingan increased speed and a simplified construction.

The nature and characteristic features of 4the invention will'inorefully appear by reference to the following description and theaccompanying drawings in illustration thereof, of which- Figure 1represents a side elevation of a braiding-machine embodying myimprovements. Fig. 2 represents a plan view thereof. Fig. 3 represents asectional view taken Fig. 4 represents a side elevation of a modifiedconstruction. Fig. 5 represents a vertical sectional view of theconstruction shown in Fig. 4. Fig. 6 represents a horizontal projection,partially in section, of mechanism for shifting the outside thread. Fig.7 represents a horizontal rojection, partially in section, of a modifiedorm of mechanism for shifting the outside thread. Fig. 8 represents aside elevation of a bobbin-carrier adapted for throwing the `mechanismfor shifting the outside thread,

and Figs. 9, 10, and 11 represent successive positions of the insidebobbin-carrying mechanism and means for passing the outside thread.

As shown in the drawings, the frame comprises a base 1, supporting theuprights 2, carrying the braiding-tube 3, through which the braidbraided at the point 3 is passed.

The driving-shaft 4, having thereon the driving-piilleys 5, isjouriialed in the bearings 6 and has fixed thereon the beveled pinion 7,which engages and drives in opposite directions the beveled spur-wheels8 and 9.

` The spur-wlieel 8 is fixed to a sleeve 10, which revolves upon thebearing-column 11, supported by the base 1. This s eeve carries andrevolves the lower or outside thread-bobbins 12 and the spider orsupport 13 for carrying the circular or cylindrical track 14.

The spur-wheel 9 is fixed to a shaft 15, which revolves within thebearing-column 11. This shaft carries and revolves the spider or support16, which carries the mechanism for revolving the upper or insidethreadbobbins 17. Journaled in relation to bearings 18, carried by thespider 16, are the pinions 19, which engage and are driven by a circularrack 20, carried by the bearing-column 11. The pinions 19 engage anddrive the pinions 21, fixed on shafts 22, which are `journaled in thebearings 23 of the spider.

The shafts 22 have fixed thereon the drivingwheels 24, having thereinthe notches 24. The wheels revolve in seats 25, formed in the carriers25, the latter being revolved within the revolving track 14 by thethrust of the wheels in their motion of translation.

The carriers 25 are held to the track 14 suitably by the guides 14 onthe track and the shoes 25, bolted to the carriers and engaging thetrack, by which the parts are readily assembled or separated and areliable connection is made.

The threads 12 from the bobbins 12, interwoven at the braiding-point 3with the threads 17 from the bobbins 17, are carried through the eyes-26and 27 and thence over the tension devices 28 and through the eyes 29 ofthe arms or thread-carriers 30, oscillating upon the fulcruins 31. Thethreads 12 are oscillated by the arms in the slots 32 of the track 14,through which they pass to the braiding-point, so that they are thrownalternately above and below the carriers 25 and the bobbins 17, themovements being timed to permit the notches 24 to pass these threadsbetween the wheels 24 and the carriers revolved thereby.

As shown in Figs. 1, 2, and 3, the arms may be oscillated by means ofthe pitinen 33, connected therewith by the pivots 34 and with therevolving eccentrics or cranks 35 by the rings 36. The eccentrics arefixed on the shafts 37, journaled in bearings 38, carried by therevolving spider 13, the shafts being revolved in their bearings by thepinions 39, fixed thereon and engaging with the spurwheel'or circularrack 40, carried by the column 11.

As shown in Figs. 4 to 8, inclusive, the arms may be oscillated by thecarriers 25 as by means of pins 41, fixed to the arms and extendingthrough slots 42 of the revolving track into position to be engaged bythe switch grooves or ways 43, formed in the carriers, the respectiveentrances to the grooves being at the elevations requiredfor engagingthe respective pins when the arms are at the limits of their respectivemOvements and the respective grooves being inclined so as to throw thearms to the opposite positions. To hold the arms in the positions towhich they are thrown for shifting the tln'eads until they are reversedby the succeeding carriers, any suitable device may be employed. Thismay be accomplished, for example, by springs 44, having the connections45 with the arms and the connections 46 with the toggle-links 47, thelatter having therein the slots 48, engaged by pintles or bosses 49,fixed to the track to permit the necessary longitudinal movement of thelink. These springs act to hold the arms against movement until theirpivotal connections with their respective togglelinks have passed thedead-centers, when they act to complete the throw of the arms by thethrusting actions they exert thereon through the links, the throw beingsuitably limited by the length of the slots 42, in which the pins 41reciprocate, Figs. 4 and 6, or the varms may be balanced approximatelyon their fulcrums and held by a brake or washer 50, opposing frictionalresistance to movement from the positions to which the arms are thrown.(See Fig. 7.)

It will now be understood that the upper and lower bobbins are revolvedin opposite directions, the carriers Jfor the upper bobbins movingwithin the track revolving with the lower bobbins, while the arms forpassing the threads from the lower bobbins alternately above and belowthe upper or inside bobbins are carried with the movable track and areoperated in synchronous relation with the upper bobbin-carriers and thenotched driving-wheels therefor.

As the carriers for the upper bobbins are, as to their masses, withinthe cylindrical track, the latter directly opposes the centrifugalaction of the -former and the binding tendency which obtains in movingcarriers on top` of a circular track is avoided, for the cylindricaltrack supports the carriers so as to prevent the twisting tendency thatobtains where the carriers are supported upon a track that does notdirectly oppose the central or resultant centrifugal force.

Having described my invention, I claiml. In a braiding-machine, arevoluble cylindrical track having slots therein, carriers revolublyconnected within said track, arms fulcrumed on and revoluble' with saidtrack for reciprocating threads in said slots, and mechanism forrevolving said track and carriers and reciprocating said arms in unison,said mechanism comprising notched disks engaging said carrierssubstantially as speciiied.

2. In a braiding-machine, a reciprocating thread-carrier and a revolublebobbin-carrier which operates said reciprocating threadcarrier,substantially as specified.

3. In a braiding-machine, a revoluble bobbin-carrier having switchingmechanism con- A nected therewith and a reciprocating threadcarrierhaving a device engaged by said switching mechanism to effect saidreciprocation, substantially as speciiied.

4. In a braiding-machine, a revoluble bobbin-carrier having waysthereon, and a reciprocating thread-carrier having a projection thereonadapted to be engaged bysaid Ways to reciprocate said thread-carrier,substantially as specified.

5. In a braiding-machine, a revoluble bobbin-carrier having waysthereon, a reciprocating thread carrier having a member adapted to beengaged by said ways to reciprocate said thread-carrier, and means forholding said thread-carrier in the position to which it is thrown,substantially as specified. n

6. In a braiding-machine, a track, a bobbin-carrier revolubly connectedto said-track, a reciprocating thread-carrier revoluble with said trackand having a member adapted to be engaged by said bobbin-carrier toeffect said reciprocation, and mechanism for driving said bobbin carrierrelatively to said track, said mechanism permitting the passage of athread from said reciprocating thread-carrier between saidbobbin-carrier and driving mechanism, substantially as specified.

In testimony whereof I have hereunto set my hand, this 12th day ofNovember, 1903, in the presence of the subscribing witnesses.

THOMAS K. OBER.
